Clinical and Microbiological Efficacy of Adjunctive Systemic Quinolones to Mechanical Therapy in Periodontitis: A Systematic Review of the Literature

Abstract

Objectives. To assess the clinical and microbiological efficacy of systemic quinolones adjunctive to mechanical therapy in periodontitis patients. Materials and Methods. A systematic review of the scientific literature was carried out. The search scheme comprised the Scopus, PubMed/MEDLINE, SCIELO (Scientific Electronic Library Online), and LILACS (Literatura Latinoamericana y del Caribe en Ciencias de la Salud) databases, together with the gray literature. MeSH terms and keywords were utilized to explore publications in all idioms. Only randomized clinical trials (RCTs) that met the selection criteria were included. Results. A total of 4 RCTs were selected. These RCTs found superior clinical and microbiological efficacy of adjunctive systemic moxifloxacin (MOX) and levofloxacin (LV) compared to subgingival debridement plus placebo. Improvements in PD and CAL were 2.4 ± 0.8 mm and 2.7 ± 0.9 mm for LV, and 1.5 ± 0.5 mm and 1.8 ± 0.5 mm for MOX, respectively. After six months of follow-up, adjunctive MOX reduced the presence of Aggregatibacter actinomycetemcomitans to imperceptible levels, while LV markedly reduced this microorganism. Some adverse events were reported in the LV group and none in the MOX group. Conclusions. Adjunctive MOX and LV improve probing depth and clinical attachment level compared with subgingival debridement alone in patients with periodontitis. The efficacy of these quinolones against A. actinomycetemcomitans was also superior.

Bacterial resistance to antiseptics used in dentistry: A systematic scoping review of randomized clinical trials

“…To the best of the authors' knowledge, this systematic scoping review is the first to consider the prevalence and proportions of antiseptic‐resistant species in patients evaluated in RCTs. Whereas adjunctive antimicrobials are helpful implements during dental practice, latent concerns occur regarding variations in the oral species as a consequence of their management 19,20 . These issues involve the three questions proposed in this scoping review.…”

Antibiotic Resistance in Patients with Peri-Implantitis: A Systematic Scoping Review

“…First, the antibiotic sensitivity outcomes in vitro do not essentially confer clinical efficacy against the target microorganisms [ 52 ]; therefore, the magnitude to which the informed laboratory results can hypothetically influence the therapy of PI is unknown [ 33 ]. Nevertheless, it is commonly documented that antibiotics lacking effectiveness against targeted bacteria under in vitro settings are unlikely to be clinically successful [ 53 , 54 ]. On the other hand, methodological differences were observed in the selected investigations, and their design does not permit a causal correlation to be established.…”

Antimicrobial resistance in patients with odontogenic infections: A systematic scoping review of prospective and experimental studies

“…To the best of the authors’ knowledge, this scoping review is the first to consider the prevalence and proportions of antimicrobial-resistant species in patients with odontogenic infections. Whereas adjunctive antimicrobials are helpful implements in the therapy of some oral cavity infections, latent concerns occur regarding variations in the oral species as a consequence of their management ( 31 , 32 ). These issues involve the three questions proposed in this scoping review.…”
